“Someone’s sitting in the shade today because someone planted a tree a long time ago.”
— Warren Buffett
A long holding period can materially change the economics of an investment, particularly when distributions are reinvested. That is the central takeaway from the 20-year total return profile of BlackRock New York Municipal Income Trust (NYSE: BNY). Using a starting investment date of September 25, 2006, and assuming all dividends were reinvested, a $10,000 investment would have grown to $66,856.94 by September 24, 2026.
BlackRock New York Municipal Income Trust is a municipal bond closed-end fund, not an operating company. That distinction matters. Returns in a municipal income fund are driven by a combination of portfolio income, changes in bond prices, interest-rate conditions, fund leverage where applicable, and the market price at which the fund trades relative to its net asset value. Over long periods, reinvested cash distributions can account for a substantial share of total return.

Put simply, each $10,000 invested in BNY in late 2006 would now be worth $66,856.94, based on the assumptions in the calculation. These figures were computed using the Dividend Channel DRIP Returns Calculator.
How Dividend Reinvestment Changed the Outcome
Dividend reinvestment was a major contributor to the ending value. Over the 20-year period, BlackRock New York Municipal Income Trust paid $20.67 per share in cumulative dividends used in this analysis. Reinvesting those distributions increased the share count from 284.58 shares to 444.92 shares, a gain of more than 56% in ownership units without any additional out-of-pocket capital.
That increase in share count matters because future distributions are then earned on a larger base. In income-oriented strategies, compounding often depends less on dramatic capital appreciation and more on the steady recycling of cash flows into additional shares over time.
What Yield on Cost Shows
Based on the most recent annualized dividend rate of $2.52 per share, BNY currently yields approximately 1.68% using the cited market price. Another useful reference point is yield on cost, which compares the current annualized dividend with the original purchase price of $35.14 per share. On that basis, the income stream represents a yield on cost of about 4.78%.
Yield on cost is not a valuation measure, and it does not describe what a new investor would earn at today’s price. It is best understood as a way to illustrate how a long-held position can generate a higher cash return relative to the original capital committed.

Why Long-Term Measurement Matters for Municipal Income Funds
For a municipal bond closed-end fund, evaluating performance through a total return lens is especially important. Market price changes alone can understate the economic value created by recurring distributions, while income alone can miss the impact of rate cycles and shifts in fund pricing. A 20-year view captures both. In BNY’s case, the combination of price appreciation and reinvested dividends produced a materially stronger result than looking at the distribution rate in isolation.
One practical conclusion stands out: when assessing income vehicles, it is useful to track not only the current yield but also how distributions affect long-term compounding, share accumulation, and ending portfolio value.
